The beneficiation process of nickel ore coppernickel

The beneficiation process of nickel ore coppernickel

The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of copper sulfide nickel ores, collectors and foaming agents for flotation of copper sulfide minerals are often used. A basic principle for determining the flotation process is that it is better to allow copper to enter the

The Application of Xanthate in Froth Flotation Process

The Application of Xanthate in Froth Flotation Process

Xanthate, as the flotation collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of flotation.Xanthate is commonly used in the flotation process of sulfide minerals. Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector. . It is light yellow, soluble in water and ...

The Critical Role of Pulp Density on Flotation Separation

The Critical Role of Pulp Density on Flotation Separation

In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation .Large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies .

Effect of a novel phosphate on the flotation of serpentine

May 01, 2020 The low-grade copper-nickel sulfide ore for flotation tests was from Yanbian Mine, Sichuan Province, China. The main compositions of the ore were 0.45 Cu, 0.63 Ni, 28.96 MgO and 33.12 SiO 2. The main sulfide minerals were pentlandite, chalcopyrite, and pyrrhotite. The main gangue minerals were serpentine, pyroxene, hornblende and chlorite.
